My legs never saw the sun. Is that why they're spotty?

I always wear dark or totally opaque pants and skirts, since I was a kid. My skin tone is naturally a Hispanic golden-brown. My legs are milky white since they never see the sun, but there are tiny brown pinpoint spots of melanin, like tiny freckles, at the base of the hair shafts on my legs. You can see them even after waxing. Does everyone have this? Will they disappear if I tan and even out the tone?
